The Sierra Club warns that carbon dioxide emissions from electricity generation could climb by 618 million tons by 2030, an output comparable to powering over 128 million homes for an entire year. Although net annual emissions declined significantly between 2007 and 2025, they began climbing again last year primarily because of digital infrastructure power needs. An academic study similarly estimated that cryptocurrency mining and computing facilities could lift power sector emissions 28 percent over baseline projections. Final emissions will ultimately be determined by the volume of projects built and the specific fuel sources used.

The US power sector could release 42 percent more planet-heating carbon dioxide pollution by 2030 than it did in 2025 as it builds out more fossil fuel infrastructure to meet data center electricity demand, according to a new analysis by the Sierra Club. That would essentially wipe out 15 years of greenhouse gas reductions.
Data centers could send US climate pollution skyrocketing
Gas plants built for data centers are poised to undo more than a decade of climate action.

CO2 emissions from electricity generation would increase by 618 million tons by the end of the decade if planned AI projects are constructed. That’s roughly equivalent to carbon pollution from the electricity use of 128,788,523 homes in a year.
The Sierra Club’s estimate is higher than some previous projections
The Sierra Club’s estimate is higher than some previous projections from other groups. Another study published by academic researchers in June forecast that electricity demand from data centers and crypto mines could push up power…
Local officials granted key regulatory approvals to establish a dedicated district for Manresa Wilds, paving the way for extensive coastal remediation on Long Island Sound. Funded entirely through private investment by Austin and Allison McChord, the initiative repurposes an industrial waterfront property while adhering to strict environmental and neighborhood controls. The multi-stage project balances ecological restoration with curated public amenities to create a sustainable regional destination.
Environment Secretary Angela Eagle has summoned industry executives to Whitehall following a joint regulatory assessment that exposed deteriorating ecological standards across the sector. Regulators awarded suppliers a record-low collective score despite billions in recent infrastructure investment. Ministers are now preparing sweeping reforms to hold leadership accountable, including blocking bonuses at the lowest-rated firms.
Justices MM Sundresh and Prasanna B Varale emphasized that unchecked air pollution harms every living being, making judicial orders a mockery when local agencies fail to execute them. Rather than imposing an immediate total prohibition, the bench is pressing regional officials to monitor ground-level compliance actively and enlist public figures to build community cooperation. Continued non-compliance by administrative authorities risks triggering far stricter judicial mandates across the National Capital Region.
